See pictures. I bought them off eBay,

The left black one, in addition to appearing very different from the known good one, exhibits signs of my old known fake non motion plus such as excessively bright blue lights, louder than normal clicky + and - butons, extra noisy/rattling motor, and Asian characters in the battery compartment (I don't mean to be ignorant but I don't know which Asian text specifically, just that it's nowhere to be seen on my known legit one). Also the questionable black one has a battery cover without a sync button, juts like my old fake one.
As for the white one it looks way more like its supposed to, but it also has the Asian characters in the battery compartment that are no where to be seen on my known legit one. If there were different cosmetic revisions I'm fine with that but if these are possible fakes I'd really rather just cut my loses for return shipping and get known genuine ones, even if they're twice as much as I paid for these.
The seller has a 14 day return policy, (I pay return shipping).
Do these seem 100% legit to you guys, or if you were me would you just cut your slight loss in return shipping and buy known genuine ones from a place like Walmart, Target, GameStop, etc.
Thanks for your time!
